Yes, it can be changed.
no but it will fit a mossburg 500
Gunshop, pawnshop, on line gun auction.
The Revelation 310A was made by Mossburg same as the 500 just go to there website and download the 500 man
Yes, you can....but the chamber on the 500 barrel is only bored for 3" max shells. You won't be able to fire 3.5" shells through the 500 barrel.
The same size forearm is used on all barrel lengths of the 500.
The only way to know which brand/weight your weapon likes is to shoot as many different types as you can afford.
no
Well, yes and no. Support should go under the forearm, not the barrel. When a support is placed under the barrel, it MAY change the point of impact. The pressure of the forearm on the barrel may change, and the normal vibration of the barrel is changed. For a hunting grade .22 rifle used to 30 yards, you probbably would not see a difference. For a long range target rifle used at 500 yards, you WILL see a difference.
Type your answer here.39..
The model with an 18.5" barrel has an overall length of 38.5", and with a 20" barrel, 41".
You will have to state who made it.
It will be printed on the barrel
